BPA HDPE LDPE PP: Water Bottles Decoded PDF Print E-mail

The United States still leads the world in consumption of single-use bottles of water. Manufacturing these luxury products wastes lots of water and petroleum....and let’s not forget the fuel spent hauling the bottles to the retailer. Recycling rates for single-use bottles have increased dramatically, but the big question is still: why buy them at all? Since the episodes of bisphenol A (or BPA) contamination from plastic bottles a couple of years ago, lots of safe refillable water bottle alternatives have surfaced. The plastic to avoid is polycarbonate, which contained BPA. You can assume that any new bottles purchased will be BPA free, but be skeptical about ones you bought before 2010.

For a rigid reuseable plastic bottle, the material of choice is polypropylene,

with Tritan (or copolyester) being a close second, because the polypro bottles are tougher. For a squeezable bottle, both HDPE and LDPE plastics make good, inexpensive, but opaque, containers. Aluminum and stainless steel have the best odor resistance among all the bottle choices. Aluminum bottles are plastic lined to avoid metallic taste, so make sure the lining is BPA free. Stainless steel bottles don’t need lining, and can withstand acidic liquids, but are a bit heavy.
